Dear statalist 

I have a data set which I would like to analyse with survival analysis and 
panel analysis.

Excerpt from my data set:
ID      Year    status 
1       2000    0                                
1       2001    0 
1       2002    0 
1       2003    1

2       2002    0
2       2003    0
2       2004    0
2       2005    0

3       2001    0
3       2002    0
3       2003    2 

4       2002    0
4       2003    3
 

For the panel analysis I would like to change the variable "status" (with 
the information on 4 different reasons (so status could be 1,2,3,3) of 
death and 0=pending) so that I have the "reason of death" in all years and 
not in the year of death.

Like this:
ID      Year    status
1       2000    1
1       2001    1
1       2002    1
1       2003    1

2       2002    0
2       2003    0
2       2004    0
2       2005    0

3       2001    2
3       2002    2
3       2003    2 

4       2002    3
4       2003    3

Could anybody help my how to replace the "0" with "1" "2" "3" "4" if the 
person is death?

Thank you for your help.

Best Frauke
